Papers in progress and submission
Gershenfeld's Law on Writing: Good papers are never finished, just abandoned.
Notes:
- The material in my PhD thesis is somewhat dated. A more up to date version
of (most of) the original content is available in my published and accepted papers.
A more polished version of the background notes on foliations is available
here.
- What the
press are saying.

"Doukipudonktan" Raymond Queneau
- Lisa's home page.
- Anna's home page.
- House renovation pictures
here.
- Boadicea,
my late pussy cat. (RIP 2003)
- I am a professor at Caltech. If
you're considering me as a PhD advisor, look here.
- Long ago, before I had kids, I (apparently) used to see a lot of movies.
This is what I thought of some of them.
- I wrote a little puzzle that runs under Linux
called rubix square.
It's put together with
graphical macros from the qt library. I think it uses .gif functions, which
are deprecated in later verions of qt, so you might need to hack it.
- Here's Carlotta's home page,
including Carlotta's Memory Game.
- I used to live in Cambridge
Massachusetts. Now I live in
Pasadena California with my wife
Tereez. Here's a nice picture of the two of us.
- My best friend William Webber is a programmer in Melbourne.
Here is a representative
picture, exemplifying our relationship.
- If you want to see a picture of
me and Tereez (nee Therese Walsh)
at our wedding, click here.
- A dinner party
at the house of Gretchen and Barry Mazur. Gretchen is in the
background.
- An OuLiPo page.
- I'm a big fan of Japanese comics,
including Urusei Yatsura and
Maison Ikkoku, of course. Also,
recently, I have been reading Osamu Tezuka's "Buddha".
- I like a lot of music. Here is a
silly piece of music I wrote. It's in mp4 format, sorry if you can't hear it.
And here's a little fugue.
- Some words.
- Ennui.
- Infra-mince.
